Abstract
The impact of unfunded medical research (ie, research conducted with no visible means of support) has received scant attention. In this study, we counted research contributions from the 10 most-cited journals in the fields of internal medicine, pathology, and surgery. Ten consecutive articles, excluding case reports and review articles, for the years 1987, 1989, and 1991 were sampled from each of 10 journals for the three areas of medicine. Unfunded articles accounted for the majority of contributions (60% of pathology articles, 62% of internal medicine articles, and 74% of surgery articles). In 1987, funded research articles published received somewhat more citations (2,961) than unfunded research articles (2,368). Among articles supported by an NIH grant, the first author of the article was seldom the grant's principal investigator (38.6%, 26.9%, and 16.7% of funded articles by pathologists, internists, and surgeons, respectively). These results indicate that unfunded research plays a major role in medical research.
